BURNING OFF, SEASONING, AND HARDENING INCANDESCENT GASMANTLES.

To all whom it may concern:

Be it known that I, MAXIM ITANSON Ilea- SEY, a subject of the King of (treat Britain and Ireland, residing at 1 15 Bethune road, Amhurst Park, in the county of London, England, have invented new and useful Improvements in Burning Oil, Seasoning, and Hardening Incandescent (ias-h'lantles, of which the following is a specification.

My invention relates to improvements in those burning-off machines for incandescent gas mantles, in which the different processes of shaping, seasoning and hardening are carried out at one operation without removing the mantles from the position in which they are first set inthe machine, by the use of Bunsen or blow pipe burners so arranged that their flames simultaneously or successively act on the interior and the upper external portion of the mantle.

My invention is designed to provide improved mechanism to facilitate and increase the production of incandescent gas mantles without the misshapen or imperfect mantles generally known in the trade as seconds.

According to my invention I provide a machine in which a movable mantle supporting ring is mounted in a framework and adapted to be moved up to the shaping, seasoning and hardening burners and is provided with a series of supports or wire frames adapted to receive and support the mantles to be operated upon.

My invention is applicable to both inverted mantles and upright mantles.

My invention. is illustrated by way of example in the accompanying drawings, in which- Figure 1 shows a side sectional view of a burning-oft machine for shaping, seasoning and hardening mantles.

Fig. 2 shows a plan view of Fig. 1;

Fig. 3 shows a detail sectional view on an enlarged scale of one element of the carrying ring and corresponding gas ring with a mantle in position;

Fig. 1 shows a plan view of Fig. 3;

Fig. 5 shows a sectional side view of a burning-off machine for shaping, seasoning and hardening upright mantles, and

Fig. 6 shows a plan view of Fig.

According to the preferred construction at present known to me I mount on a pair of uprights a vertically movable mantle sup- Patented All. 6, 1918.

porting ring carrimlv by sleeves sliding upon said uprights.

Referring now to Figs. 1, 2, 3 and 4: of the drawings: A mantle ring 1 is provided with a series of wire supports or frames 2. The mantles 4t are adapted to rest on said wire frames 2 in plates 3 in which they have been previously mounted and to project downward through said :fran'ies, as shown in Fig. 3. Above the ring 1 1 mount a circular gas ring 5 connected with the high pressure main through the gas connection 10. This ring 5 is stationary and is provided with a series of downwardly projecting seasoning burners (3 respectively adapted to register and to enter the interiors of the mantles l suspended in said sliding ring when the ring is raised by the chain 7 upon the uprights 8, which uprights are embraced by the sleeves 9 supporting the ring 1 upon the said uprights. Beneath the sliding ring 1 I arrange a gas ring 11 of larger diameter than the ring 5 provided with a series of inwardly projecting hollow rings 12 with burner perforations on their inner surfaces. These rings 12 register with the wire frames on the sliding ring 1. The said rings 12 are adapted to encircle the mantles when the supporting ring is lowered on to the gas ring and operate to harden the upper parts of the mantles where they are connected with their mantle rings. The top surface of the gas ring 11 allows of the ring 1 being lowered to a plane level with the high pressure flilll'lCS issuing from the burner rings 12, thus allowing of the collars of the mantles being seasoned. The hardening of the mantle is obtained by intensifying the Bunsen lame by altering the proportions of gas and air.

In Fig. 5 and (5 I show a machine adapted for the manufacture of upright mantles. In such a construction the sliding mantle supporting ring 15 is arranged above the gas burners 6 and 12. The upright mantles are suspended from the sliding ring 15 by means of hooks 17 adapted to register with the vertical axes of the said seasoning and shaping burners (i and 12. The sliding ring 15 with the mantles suspended therefrom is adapted to be lowered into a position in which said mantles 16 pass through the ring shaping burners 12, while the upwardly projecting seasoning burners 6 beneath said ring project into the interiors of the mantles 16.

In this manner the mantles are simultaneously shaped, seasoned and hardened. Limiting collars 18 are provided in order to allow of burning-off on the same machine of'difterent sizes of mantles.

What I claim is 1. A machine for burning-off, seasoning and hardening incandescent gas mantles comprising a guiding framework, a mantle supporting ring mounted upon said framework, means for moving said mantle supporting ring, a series of supports mounted on said ring and adapted to hold in their normal position the mantles to be operated upon, two gas rings mounted on said framework, a single air inlet for each gas ring and means for gas ring movement upon the said guiding framework.

2. A machine for seasoning incandescent gas mantles comprising a framework, a gas ring mounted upon said framework, a mantle supporting ring mounted upon said framework, a series of seasoning burners projecting from said gas ring at right angles to the plane of the ring and adapted to register with and enter the interiors of the mantles held in said supporting ring and means for moving'the mantle supporting ring toward said seasoning'burners.

3. A machine for burning-off and hardening incandescent gas mantles comprising a guiding framework, a gas ring mounted uponsaid framework, a series of burners inwardly projecting from said gas ring and formed as hollow rings with burner perforations on their inner surfaces and each adapted-to encircle a mantle and to be passed over it up to the mantle ring, means for moving the mantle supporting ring toward the said gas ring and means adapting said gas ring to slide to or from the mantle supporting ring upon the guiding framework.

4. A machine for burning-off, seasoning and hardening incandescent gas mantles comprising a guiding framework, a mantle Copies of this patent may "be obtained for HIQHIIS supporting ring mounted upon said frame work, means for moving said mantle supporting ring upon the framework, a serles of supports mounted upon said ring and adapted to hold in their normal position the mantles to be operated upon, a gas ring mounted on said framework above said supporting ring, a series of seasoning burners projecting from said ring and adapted to register with and enter the interiors of the mantles held in said supporting ring, a single air inlet for said gas ring, a second gas ring mounted on said framework beneath said mantle supporting ring, a series of burners inwardly projecting from said gas ring and formed as hollow rings with burner perforations on their inner surfaces and each adapted to encircle a mantle and to be passed over it up to the mantle ring, a single air inlet for said gas ring, means for moving the mantle supporting ring toward each alternately of said gas rings and means normal position the mantles to be operated upon, two gas rings mounted on said framework, a single air inlet for each gas ring, means for gas ring movement upon the said guiding framework, and adjustable limiting mounted upon said framework adapted to limit the movement of the mantle supporting ring to or from a gas ring.

In testimony whereof I sign my name to this specification in the presence of two subscribing witnesses.
